The UDP3303C is the SCPI-programmable counterpart to the UDP3303A — same 195W three-channel linear hardware, same CH3 logic-rail selector cycling 1.8V / 2.5V / 3.3V / 5V at 3.2A, same ≤1 mVrms ripple — with a back-panel USB-Device port and RS-232 added for full SCPI control. CH1 and CH2 deliver 0–30V at 0–3A; series and parallel modes extend that to 60V or 6A.
Programming accuracy holds inside ≤0.1% + 30 mV on voltage and ≤0.5% + 2 mA on current — fine enough for sleep-mode current characterization on IoT prototypes, battery-charge cut-off testing, and any automated sweep that needs the setpoint to land exactly where you asked it. Five preset storage groups (M1–M5), shutdown memory, OVP / OCP / OTP per channel, and a Digital I/O hardware ON/OFF pin pair round out a programmable supply built for benches that have to behave the same way every time. For 5A per adjustable channel, see the UDP3305C; for the knob-only manual variant, see the UDP3303A.
